About this creation

Libra Mecha aka 'Dusty Mecha' ----- Background & Construction

The Libra mecha holds the distinction of being the first Zodiac
mecha off the line. The nickname 'Dusty' comes from it's colorscheme.
Tan and grey are the preferred colors of the desert dwellers of
Tsarios. The Libra mecha earned it's name through the perfect
balance of speed and weaponry. Every other Zodiac mecha begins
with the simple statistics that the Libra posesses, and is modified
from that point on. As our flagship product, we are quite proud
of this mecha, as no competing company has produced a comparable
product for the price.

Future modifications to the Libra would include altering the colorscheme
for other civilizations and creating an extra pair of 'arms' for
additional speed/firepower.
